!IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Be sure that the power cord is unplugged before disassembling orassembling parts of the copier or peripherals.
2. The wall outlet should be near the copier and easily accessible.
3. Note that electrical voltage is supplied to some components of the copierand the paper tray unit even while the main power switch is off.
4. If you start a job before the copier completes the warm-up or initializingperiod, keep hands away from the mechanical and electrical componentsuntil job execution has started. The copier will start making copies as soonas warm-up or initialization is finished.
5. The inside and the metal parts of the fusing unit become extremely hot while
the copier is operating. Be careful to avoid touching those components withyour bare hands.
HEALTH SAFETY CONDITIONS
Toner and developer are nontoxic, but getting either of these into your eyes maycause temporary eye discomfort. Try to remove with eye drops or flush withwater. If material remains in eye or if discomfort continues, get medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
The copier and its peripherals must be installed and maintained by a customerservice representative who has completed the training course on those relevantmodels.
LITHIUM BATTERIES
Incorrect replacement of lithium battery(s) on the FCU may pose risk ofexplosion. Replace only with the same type or with an equivalent typerecommended by the manufacturer. Discard used batteries in accordance withthe manufacturers instructions.

LASER SAFETY
The Center for Devices and Radiological Health (CDRH) prohibits the repair oflaser-based optical units in the field. The optical housing unit can only be repairedin a factory or at a location with the requisite equipment. The laser subsystem isreplaceable in the field by a qualified Customer Engineer. The laser chassis is notrepairable in the field. Customer engineers are therefore directed to return allchassis and laser subsystems to the factory or service depot when replacement ofthe optical subsystem is required.
!WARNINGUse of controls not specified in this manual, or performance ofadjustments or procedures not specified in this manual, may result inhazardous radiation exposure.
!WARNING FOR LASER UNITWARNING: Turn off the main switch before attempting any of the
procedures in the Laser Unit section. Laser beams can causeserious damage to eyes.

3. REPLACEMENT AND ADJUSTMENT
3.1 PRECAUTIONS
3.1.1 GENERAL
!CAUTIONTurn off the main power switch and unplug the machine before starting anyof the replacement procedures described in this section.
But note that you should not turn off the main switch while mechanical parts areactive, as this may cause parts to stop out of home position. Attempting to removeor install the PCU or other such units while parts are out of home position mayresult in damage. Wait for operation to stop before turning off the machine.
3.1.2 LITHIUM BATTERIES
!CAUTION: Lithium BatteriesIncorrect replacement of lithium battery(s) on the FCU poses risk ofexplosion. Replace only with the same type or with an equivalent typerecommended by the manufacturer. Discard used batteries in accordancewith the manufacturers instructions.
3.1.3 PCU (PHOTOCONDUCTOR UNIT)
The PCU consists of the OPC drum, charge roller, development unit, and cleaningcomponents. Observe the following precautions when handling the PCU.
1. Never touch the drum surface with bare hands. If the drum surface is dirty or ifyou have accidentally touched it, wipe it with a dry cloth, or clean it with wetcotton and then wipe it dry with a cloth.
2. Never use alcohol to clean the drum. Alcohol will dissolve the drum surface.
3. Store the PCU in a cool dry place.
4. Do not expose the drum to corrosive gases (ammonia, etc.).
5. Do not shake a used PCU, as this may cause toner and developer to spill out.

3.1.5 SCANNER UNIT
1. Use alcohol or glass cleaner to clean the exposure and scanning glass. Thiswill reduce the static charge on the glass.
2. Use a blower brush or a water-moistened cotton pad to clean the mirrors andlenses.
3. Take care not to bend or crease the exposure lamps ribbon cable.
4. Do not disassemble the lens unit. Doing so will throw the lens and copy imageout of focus.
5. Do not turn any of the CCD positioning screws. Doing so will throw the CCD outof position.
3.1.6 LASER UNIT
1. Do not loosen or adjust the screws securing the LD drive board on the LD unit.Doing so will throw the LD unit out of adjustment.
2. Do not adjust the variable resistors on the LD unit, as these are permanentlyadjusted at the factory. If replacement of the LD drive board is necessary,replace the entire LD unit.
3. Keep the polygon mirror and toroidal lens free of dust. Laser performance isvery sensitive to dust on these components.
4. Do not touch the shield glass, the lenses, or the surface of the polygon mirrorwith bare hands.
3.1.7 FUSING UNIT
1. After installing the fusing thermistor, make sure that it is in contact with the hotroller and that the roller can rotate freely.
2. Be careful to avoid damage to the hot roller stripper pawls and their tension
springs.3. Do not touch the fusing lamp and rollers with bare hands.
4. Make sure that the fusing lamp is positioned correctly and that it does not touchthe inner surface of the hot roller.

BThese SCs can be cleared by turningthe main power switch off and on.
Turn the main power switch off and on.
NOTE: 1) If a problem involves circuit boards:Before deciding to replace a circuitboard, first see if you can solve the problem by disconnecting and thenreconnecting all connectors.
2) If a problem involves a motor lock:Check the mechanical load first,before deciding whether to replace motors or sensors.
3) If working on a fax-equipped machine, keep in mind that switchingpower off and back on may in some cases cause loss of data stored inSAF memory.
